Couple of things...as a newbie, how did you make the lager? Was it all grain? Also, I agree that lager's are tricky to get done right and taste right. If you do not have a naturally cooled <55* room in your house then you must have set up a lagering fermentor which means you are well beyond newbie skills.

So if you have done lagers and are already on all grains, not sure what you are asking. The adjuncts them selves are only dollars a piece, there are lots of places with recipies on making your own belgian candy sugars if you do not want to buy (homebrewtalk.com)

(Did you really mean lager?)

If you have not gone all grain, and made an extract kit, are you ready for all grain? You will need a mash tun to mash the grains in, you will need a much bigger boil pot than an extract boil pot, you migh need a cooler of some kind since you will not be adding water to cool, you will need to learn how to make large yeast starters to deal with the high gravities, possibly even need some yeast nutrients. If you are making a very big beer with lots of yeasts, you will also need to make sure that when she blows (and she will) that you have blow off tubes and buckets and can clean where ever the foam got to.
